Abstract

Data packets containing source and destination addresses are received on one or more incoming ports for distribution on one or more outgoing ports. An address look-up table stores previously processed source and destination addresses, together with source and destination contexts associated with the respective source and destination addresses. The contexts represent either a specific physical port, or an aggregated grouping of ports. A distribution table stores, for each aggregated grouping of outgoing ports, a corresponding aggregated group of identifiers of specific outgoing ports. As each packet is received, its source and destination addresses are extracted and the address look-up table is searched for those source and destination addresses. If the address look-up table contains those source and destination addresses then the source and destination contexts associated with those source and destination addresses are retrieved from the address look-up table. If the address look-up table does not contain a source address corresponding to the extracted source address, then a source context corresponding to the extracted source address is derived and stored in the address look-up table with the extracted source address. If the retrieved destination address context represents a specific outgoing port, then the received packet is queued for outgoing transmission on that port. If the retrieved destination address context represents an aggregated grouping of outgoing ports, then the identifiers for the outgoing ports comprising that grouping are retrieved from the distribution table, and the received packet is queued for outgoing transmission on all of the outgoing ports comprising that grouping.
